We would like to use several sensors to measure the fine dust particles near the highway under different circumstances over a longer period of time, then save them and evaluate them afterwards. Would it be possible to save this data on an SD card, as we do not have wifi at our measuring locations?
We also need some help with programming the sensors.
Thank you in advance!
Hello,
for this use case you should look for other ‘systems’ than ours. We only support data transmission via wifi and saving the data on our servers.
There are some projects using the SDS011 and a raspberry pi (found by a gogle search):

Quite some time ago I built one using Espeasy as firmware. They have.drivers for sensors and - I personally haven’t used it, but it’s possible to add a SD-card, too.
You can check both at espeasy.readthedocs.io
